Here is some code for sending a test email with the GMail API:
public bool SendTestEmail(string From, string Subject, string Body)
{
try
{
MailMessage mail = new MailMessage();
mail.Subject = Subject;
mail.Body = Body;
mail.From = new MailAddress(From);
mail.IsBodyHtml = false;
mail.To.Add(new MailAddress(From));
MimeKit.MimeMessage mimeMessage = MimeKit.MimeMessage.CreateFromMailMessage(mail);
Message message = new Message();
message.Raw = Base64UrlEncode(mimeMessage.ToString());
var result = m_Service.Users.Messages.Send(message, "me").Execute();
}
catch (Exception ex)
{
SimpleLog.Log(ex);
return false;
}
return true;
}
It works fine. However, my email settings window in my application caters for other SMTP hosts and as a result has other settings:
Is it possible to feed to the GMail Service:
Port number
SSL/TLS mode
Server Timeout
Or don’t these apply when sending emails like this?

My application have function to sent email trough smtp.gmail.com
It works well when i run at local, but after i publish to vps, the email not sent.
dns setting for mx(10) was pointing to smtp.gmail.com
here's the code that i use :
public ServiceResult SendEmailOrder(string Email)
{
ServiceResult result = new ServiceResult();
try
{
const string fromPassword = "password";
MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient();
mail.From = new MailAddress("senderaddress#gmail.com");
mail.Subject = "subject mail";
mail.Body = "Body Mail";
SmtpServer.Port = 587;
SmtpServer.Credentials = new System.Net.NetworkCredential("senderaddress#gmail.com", fromPassword);
SmtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
SmtpServer.Host = "smtp.gmail.com";
SmtpServer.EnableSsl = true;
mail.To.Add(new MailAddress(Email));
SmtpServer.Send(mail);
}
catch (Exception ex)
{
result.Error("Failed Send Email", ex.InnerException.Message);
}
return result;
}
is that something that i missing?
*note :
- my vps was connect to internet,
- i use google cloud before, and the code works well.
The code I currently have is:
public void SendEmail(string to, string cc, string bcc, string subject, string body, string attachmentPath = "", System.Net.Mail.MailPriority emailPriority = MailPriority.Normal, BodyType bodyType = BodyType.HTML)
{
try
{
var client = new System.Net.Mail.SmtpClient();
{
client.Host = "smtp-mail.outlook.com";
client.Port = 587;
client.UseDefaultCredentials = false;
client.EnableSsl = true;
client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
client.Credentials = new NetworkCredential("[my company email]", "[my password]");
client.Timeout = 600000;
}
MailMessage mail = new MailMessage("[insert my email here]", to);
mail.Subject = subject;
mail.Body = body;
client.Send(mail);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
The email address I'm trying to send to is hosted on Office 365's Outlook. We might have to change the specific address later, but they'd likely be configured the same.
However, whenever I try to run the client.Send(mail); command, I receive the same error. The full text of the error is:
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM
I've tried a few different things, like switching the port between 25 and 587, changing the host to Office365's, or toggling UseDefaultCredentials and EnableSssl to true or false. But I always see the same error. Is there something else I'm missing?
I found an example code block elsewhere on this site and replacing everything I had with it made the difference.
The function name and parameters were the same, but here's what I replaced the body of it with.
var _mailServer = new SmtpClient();
_mailServer.UseDefaultCredentials = false;
_mailServer.Credentials = new NetworkCredential("my email", "my password");
_mailServer.Host = "smtp.office365.com";
_mailServer.TargetName = "STARTTLS/smtp.office365.com";
_mailServer.Port = 587;
_mailServer.EnableSsl = true;
var eml = new MailMessage();
eml.Sender = new MailAddress("my email");
eml.From = eml.Sender;
eml.To.Add(new MailAddress(to));
eml.Subject = subject;
eml.IsBodyHtml = (bodyType == BodyType.HTML);
eml.Body = body;
_mailServer.Send(eml);
I don't know for certain but I think that replacing the Host value with the smtp Office 365 link rather than an outlook one, as well as remembering to add a Target Name which I did not have before, both did the trick and solved the authorization issue (I had previously confirmed it wasn't a credentials issue with our tech support).
I am using Smtp to send mail.A message was sent successfully but it was not delivered. What is the reason behind this.Is this a problem in mailing server?The message sending process is working fine for the last couple of years.The issue came first time.
public bool SendMail(string p_strFrom, string p_strDisplayName, string p_strTo, string p_strSubject, string p_strMessage , string strFileName)
{
try
{
p_strDisplayName = _DisplayName;
string smtpserver = _SmtpServer;
SmtpClient smtpClient = new SmtpClient();
MailMessage message = new MailMessage();
MailAddress fromAddress = new MailAddress(_From,_DisplayName);
smtpClient.Host = _SmtpServer;
smtpClient.Port = Convert.ToInt32(_Port);
string strAuth_UserName = _UserName;
string strAuth_Password = _Password;
if (strAuth_UserName != null)
{
System.Net.NetworkCredential SMTPUserInfo = new System.Net.NetworkCredential(strAuth_UserName, strAuth_Password);
smtpClient.UseDefaultCredentials = false;
if (_SSL)
{
smtpClient.EnableSsl = true;
}
smtpClient.Credentials = SMTPUserInfo;
}
message.From = fromAddress;
message.Subject = p_strSubject;
message.IsBodyHtml = true;
message.Body = p_strMessage;
message.To.Add(p_strTo);
try
{
smtpClient.Send(message);
Log.WriteSpecialLog("smtpClient mail sending first try success", "");
}
catch (Exception ee)
{
Log.WriteSpecialLog("smtpClient mail sending first try Failed : " + ee.ToString(), "");
return false;
}
return true;
}
catch (Exception ex)
{
Log.WriteLog("smtpClient mail sending overall failed : " + ex.ToString());
return false;
}
}
A message was sent successfully but it was not delivered
If it was sent successfully from your mailing server then the possible reason of non delivery can be that the mail filter on client blocked it or is delivered in the junk.

This mail code is working in localhost i.e on my computer but when i uopload it on server it is not working.
The error is : Failure sending mail. please tell me where is the problem.
if (Session["userinfo"] != null)
{
lblTest.Text = Session["userinfo"].ToString();
MailMessage msg = new MailMessage();
msg.From = new MailAddress("shop.bcharya#gmail.com");
msg.To.Add(new MailAddress("bcc#dr.com"));
msg.To.Add(new MailAddress("info#yzentech.com"));

For gmail mail settings add Port number too
sc.Port = 587;
after this line
sc.Host = "smtp.gmail.com";
Only use port 587 and SSL if the SMTP server supports that (GMail and Hotmail for example). Some servers just use port 25 and no SSL.
Use below method and then check :
SmtpClient sc = new SmtpClient(string); //sends e-mail by using the specified SMTP server
You can use this below given code for sending email. Here sending the error details through email is one method. Try this code for sending email.
using System.Web.Mail
public static bool SendErrorEmail(string to, string cc, string bcc, string subject, string body, MailPriority priority, bool isHtml)
{
try
{
using (SmtpClient smtpClient = new SmtpClient())
{
using (MailMessage message = new MailMessage())
{
MailAddress fromAddress = new MailAddress(“yourmail#domain.com”, “Your name”);
// You can specify the host name or ipaddress of your server
smtpClient.Host = “mail.yourdomain.com”; //you can specify mail server IP address here
//Default port is 25
smtpClient.Port = 25;
NetworkCredential info = new NetworkCredential(“yourmail#domain.com”, “your password”);
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = info;
//From address will be given as a MailAddress Object
message.From = from;
message.Priority = priority;
// To address collection of MailAddress
message.To.Add(to);
message.Subject = subject;
// CC and BCC optional
if (cc.Length > 0)
{
message.CC.Add(cc);
}
if (bcc.Length > 0)
{
message.Bcc.Add(bcc);
}
//Body can be Html or text format;Specify true if it is html message
message.IsBodyHtml = isHtml;
// Message body content
message.Body = body;
// Send SMTP mail
smtpClient.Send(message);
}
}
return true;

I have my code here, it works fine from my home, where my user is administrator, and I am connected to internet via a cable network.
But, problem is when I try this code from my work place, it does not work. Shows error:
"unable to connect to the remote server"
From a different machine in the same network:
"A socket operation was attempted to an unreachable network 209.xxx.xx.52:25"
I checked with our network admin, and he assured me that all the mail ports are open [25,110, and other ports for gmail].
Then, I logged in with administrative privilege, there was a little improvement, it did not show any error, but the actual email was never received.
Please note that, the code was tested from development environment, visual studio 2005 and 2008.
Any suggestion will be much appreciated.
Thanks in advance

Here is some sample code that works for me and talks to a gmail server
private void SendEmail(string from, string to, string subject, string body)
{
MailMessage mail = new MailMessage(new MailAddress(from), new MailAddress(to));
mail.Subject = subject;
mail.Body = body;
SmtpClient smtpMail = new SmtpClient("smtp.gmail.com");
smtpMail.Port = 587;
smtpMail.EnableSsl = true;
smtpMail.Credentials = new NetworkCredential("xxx#gmail.com", "xxx");
// and then send the mail
smtpMail.Send(mail);
}
Try setting UseDefaultCredentials to false.
Also try switching SSL on for y7mail
mail_client.EnableSSL = true;

This is the best answer for System.Exception Problem. Totally verified, you need to provide username and password at network credentials. Also try to give this solution to other sites.
